Obj-Proger/BookingHub ? reverse-engineered prompt

Build me a multi tenant appointment booking app for service businesses like salons, clinics, or consultants.

I want a backend plus a customer facing website, and a simple staff experience too. Guests should be able to browse a business, pick a service, see available times, book an appointment, reschedule or cancel it from a link, join a waitlist if something opens up, and leave a review after the visit. Staff should be able to manage services, team members, locations, schedules, settings, bookings, and reviews. Please include basic login and role based access, and make it work cleanly for more than one business in the same system.

Use the project setup that is already in the repo, with the API, web app, and mobile app pieces wired together. Keep local development simple with Postgres and sensible defaults, and add seed data so I can try the full flow right away. If you need to check anything, look up the current docs online and follow the patterns already used in the repo.
